10 Programmer Disconnect — Accessory Manual for Retrofil CB DEH-41532 02/12
4. If the customer has chosen to install a 19-pin programmer disconnect assembly in place of a 12-pin programmer
disconnect assembly, the terminal block mounted on the compartment needs to be removed as well. This can be
done by unfastening the two screws that secure the terminal block to the side wall of the compartment.
5. Unfasten the 4 bolts ( Figure 12 ) that hold the programmer disconnect assembly on the wall of the compartment
to remove the compartment side programmer disconnect assembly.

Install 19-Pin Programmer Disconnect (Compartment and Breaker)
1. Unpack the 19-pin programmer disconnect assembly from the box. Each box of programmer disconnect assembly
has a 20-pin terminal block supplied.
2. Check that the programmer disconnect plug assembly is not damaged and the wiring is intact.
3. Check that the programmer disconnect block is moving freely within the assembly and retracts to its original
position by spring loading when it is slid back to its fully activated state.
4. Check for electrical continuity between the contact pins on one and and the wire termination on the other.
Blocks containing faulty pins should not be used for installation.
5. Install the new terminal block on the side wall of the the compartment and land the incoming wires from the
compartment to the terminal block. Any additional wires from the compartment side, required for the 19 pin
programmer, need to be landed on the terminal block and checked for electrical continuity.
6. Mount the programmer disconnect assembly on the side wall of the compartment where the original programmer
disconnect assembly was mounted.
7. Land the wires from the programmer disconnect to the terminal block mounted earlier.
8. Check for continuity between the terminal block contact points to the corresponding pins on the programmer
disconnect. This should match against the wiring scheme planned for the new 19-pin programmer disconnect
assembly on the compartment.
